Low Torque AV Gaskets Standard Features (Sizes 1/2” - 12”) • PTFE or PVDF-bonded EPDM for maximum corrosion resistance • Perfect sealing at low bolt tightening torque ratings, longer gasket life • Ideal for plastic piping systems, as well as metal or plastic-lined metal systems • Sulfur cured • Durometer: Dimensions Recommended(Sizes 1/2” - 12”) (in.) Bolt Torque* 1) EPDM: 2) PTFE-bonded: 3) PVDF-bonded: Working temperature: 1) EPDM: 2) PTFE-bonded: 3) PVDF-bonded: • Approximately a one-third bolt tightening torque rating as compared with flat or envelope type gasket. • Thickness of bonded materials PTFE: All Sizes: 0.016" (0.4mm) • PTFE-bonded gasket excellent for most corrosive chemicals • PVDF-bonded gasket is ideal for the following: 1] Semiconductor industry, because of its purity 2] Aggressive chemicals (strong acids, bases, halogens, etc.) 3] Media that generates any volatile gas (PVDF gas permeation is only 1/50 of PTFE) • Both the PTFE and PVDF-bonded gaskets employ a proprietary laminating process for bonding to EPDM, providing the greater elasticity required for lower sealing torques NOMINAL SIZE NOMINAL SIZE PVDF or PTFE-Bonded Gasket EPDM Gasket Sample Specification All AV gaskets shall be of low torque, full face to ANSI B16.5 dimensions and shall have two concentric, convex, molded rings between center hole and bolt hole circle in EPDM, PTFE-bonded EPDM or PVDF-bonded EPDM, as manufactured by Asahi/America, Inc.
